SELF-.OILING WH ETSTONE.

SPECIFICATION forming` part of Letters Patent N o. 734,137, dated July21, 1908.

Application filed November 22, 1902. Serial No. 132,458. (No model.) l

To all whom it may con/cern:

Be it known that LFREDERICK REISSMANN, a citizen of the United States,residing at Westpoint, in the county of Orange and State of New York,have invented certain new and useful Improvements in Self-Oiling Whetstones; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it Vappertains to make and use the same. Y Y

My present invention relates to whetstones, and more particularly tothat variety thereof wherein an automatic self-loiling attachment isprovided; and my invention `consists in certain novel features ofcombination and construction of parts, whichvwill be hereinafter clearlyset forth, and pointed out in the claim.

The prime object of my invention, among others, is to provide a suitableoil holdingand discharging attachment designed to be convenientlydisposed within the usual box or casing employed to hold the stoneproper whereby the surface of the stone will be properly supplied with asuitable lubricant of any desired variety, and the constructionnecessary to materialize this idea will be fully illus,-`

trated in the accompanying'drawings, which are made a part of thisapplication, and in which- Figure l shows arperspective view of myVinvention complete ready for use. Fig. 2 is av provide a seat for theWhetstone proper, 2, aV suitable lid 3 being also provided to l inclosethe upper half of the stone, asis usual with appliances of this kind.The lid-section is designed to carry the oil attachment adapted tocoperate with the whetstone, whereby the upper exposed surface thereofis supplied With the requisite amount of oil, as will be hereinaftermore particularly set forth. Within the upper portion of the lid 3 thusor otherwise provided I locate the movable plate 4,which is providedwith, preferably, two controlling buttons or extensions 5, designed totake loosely `through suitable apertures 6, provided in a'contiguouspart of the center of the lid, as more clearly shown in Fig. l. Thebed-plate 4 is of proper size to fit loosely within the upper part ofthe lid 3 and is held normally upward by means of the oil-spring '7 orthe equivalent thereof, which extends through suitable apertures 8,provided in the lid. The lower en d of the spring 7 is connected to theplate 4 in any preferred way,

while the upper end thereof is bent to form the eye 9, through which theretaining or anchoring pin 10 is extended, whereby the plate will beheld from casually slipping out of place. l

To the lower side of the plate 4 I glue or otherwise secure the cushion1l, formedof felt, cloth, or other absorbent material suit-. able forthe purpose, as said substance is designed to constitute theoil-reservoir, inasmuch as it is to be kept thoroughly saturated withoil, which will at all times be kept free from grit and allV otherforeign andinjurious substances.

\ In some instances I prefer toform an aperture 12, preferably inAthrecentral portion of the push-button or extension 5, through whichoil maybe readily introduced to the reservoir of absorbent l materiall1, inasmuch as the aperture 12 is designed to register with thecorresponding aperture formed in the plate 4.

By the arrangement herein described it will be seen that while theoil-absorbent cushion 1l is heldnormally out of engagement with thesurface of the stone 12 such cushion may be readily forced downward intocontact with the stone by a simple pressure upon one or both of thebuttons 5, thus bringing the entire surfaces of the stone andcushioninto gentle contact with each other and insuringthat theoil-saturated cushion will'evenlydistribute over the surface of v thestone a proper IOO will be deposited upon the stone, whereas a greatpressure will insure that a greater quantity of oil will be deposited.

It is obvious that when the oil-ducts l2 are not provided theinnersurface of the absorbent cushion 11 may be supplied With the properquantity of lubricant, though it is thought that best results willfollow when the oil is introduced in the manner explained through theapertures 12, inasmuch as the oil will be strained, and thereby purifiedfrom any gritty substances or the like before it percolates through thematerial forming the cushion.

Various modifications may be made in carrying out my invention, inasmuchas it is obvious that other forms of springs may be employed foraccomplishing the same result, and I therefore do not wish to beconfined strictly to the exact showing herein presented, but Wish tocomprehend all substitutes and equivalents that may be considered asfairly falling Within the scope and purview of my invention.

My improved self-oiling attachment may be readily applied as anattachment upon oilstones as now constructed by the simple addition ofthe parts carrying the cushion and the means afforded to actuate thesame, as hereinbefore described.

Believing that the advantages and manner of constructing my improvedself-oiling ap# pliance for Whetstones or the like will thus be madeclearly apparent from the foregoing specification, considered inconnection with the accompanying drawings, further description is deemedunnecessary.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The herein-described attachment for oilstones or the like comprising thecombination with the lid of the casing of a movable plate-section 4having extensions or buttons 5 protruding through the casing, means tohold said plate normally upward; a cushion of absorbent material carriedby the lower surface ot' said plate whereby when saidv plate is pusheddownward the surface of the stone will be brought in contact With saidcushion and thereby supply the former with the requisite amount oflubricant all combined substantially as specified and for the purposeset forth.

In testimony whereof I ailix my signature in presence of two Witnesses.

FREDERICK REISSMANN.
